&BEGSTACK STATEMENT EXEC statement Use the &BEGSTACK control statement to delimit the beginning of a list of one or more data lines to be placed in the console stack. The list of lines to be stacked is terminated by the control statement &END which must occur beginning in column 1. The format of the &BEGSTACK control statement is: +-----------+-----------------------------------------------------------------+ | &BEGSTACK | [FIFO|LIFO] [ALL] | +-----------+-----------------------------------------------------------------+ where: FIFO specifies that the lines that follow are to be stacked on a first in, first out basis. This is the default value. LIFO specifies that the lines that follow are to be stacked on a last in, first out basis. ALL specifies, for fixed-length EXEC files, that the entire line (to a maximum of 130 characters) is to be stacked. If ALL is not specified, the lines are truncated in column 72. Usage Notes: 1. Lines that are stacked as the result of an &BEGSTACK control statement are not scanned by the EXEC interpreter. Therefore, no variable substitution is performed, and data items are not truncated. To stack variable data, you must use the &STACK control statement. 2. To stack a null line in an EXEC file you must use the &STACK control statement. A null line following an &BEGSTACK control statement is interpreted as a line of blanks. To stack an INPUT, REPLACE, or CHANGE subcommand to enter input mode from a fixed-length EXEC, you should use the &STACK control statement.
